Temperature Check


Stealth
 Share

Question

Hi, Can someone help?

 

I have an HC2 and I have been several hours trying to figure out how to write some LUA code to check the temperature of my Solar Thermal panel and if its at least 10 degrees hotter than my water tank to then switch the pump on. I worked out how to do the comparison check between the two temp sensors but my issue is how do I do the the same but check its at least 10 degrees hotter.  I also only need to run the pump between the hours of 8am to 10pm each week day.

 

Any help would be appreciated.

 

local SolarTemp     = 735    -- ID number Solar temperature sensor

local TankTemp     = 744    -- ID number Water Tank temperature

 

local SolarTemp   = fibaro:getValue(735, "value") -- Temperature Solar

local TankTemp   = fibaro:getValue(744, "value") -- Temperature Tank

 

if

               SolarTemp more than 10 degrees higher than TankTemp

                              Then

                              Turn Solar Pump On

        else

               Turn Solar pump off

 

   end

I have started to relpy you and later i noticed that you need the code for HC2. I dont know HC2, but i think it should be very similar, or at least you can get some hints from this..

I didnt test it, but i think it should work..

  • Thank you for your reply.

     

    I tried the following code with the QuickApp commented out as there are no QuickApp's in HC2 to my knowledge-

     

     

    --function QuickApp:loop()


    local ctime = os.date('%H:%M')    
    local cday = os.date('%w')
    local SolarTemp = fibaro.getValue(735,"value")
    local TankTemp = fibaro.getValue(744,"value")  
      
        self:debug("Checking Solar temp and TankTemp...")

          if ctime > "08:00" and ctime < "22:00" and cday > 0 and cday < 6 and (SolarTemp > TankTemp + 10) then
            self:debug("Starting the pump...")
            --HERE START THE PUMP    
            fibaro.call(pumpID,"turnOn")
         else
            self:debug("Stopping the pump...")
            --HERE STOP THE PUMP
            fibaro.call(pumpID,"turnOff")
        end    
     
        --CHECK EVERY 15 MIN
        fibaro.setTimeout(1000*60*15, function() 
            self:loop()
       end)

     

    I'm getting the following debug error -

     

    [DEBUG] 08:32:00: 2023-01-23 08:32:00.075955 [ fatal] Unknown exception: /opt/fibaro/FibaroSceneAPI.lua:116: attempt to concatenate local 'propertyName' (a nil value)

    You cant just comment out the function...Please wait for someones advice, who is familiar with HC2 usage...

  • Can anyone help advise what's wrong with this code when run on a HC2 please?

     

    I want to run an if check to start a pump when the SolarTemp sensor is 10 degrees hotter than the TankTemp.

    My friend, please dont use this code likt this...I wrote it for HC3, and it is a LOOP function..In this way it will not work..

    On the other hand, you need to replace the "pumpID" variable with the real ID of your pump device..What is you pump ID?

    I really dont know what is the HC2 syntax, but for sure the code will not work if you dont define the pumpID variable, or replace it with the ID of the pump.

  • Hi thank you for your reply. The pump ID is 145

     

    regards

    Hello @Stealth ,

     

    Here is a simple code for the HC2 LUA scene:

    Please login or register to see this code.

    Scene will run every time when any of the temperature change and either start or stop the pump. To save some z-wave traffic, command for pump to start or stop will be sent only if necessary.

    Scene will check temperatures and start or stop the pump only between time set by from_time and to_time. Outside this period pump will be stopped if running or no action will be executed.

     

    NOTE - you can remove temperature sensors from scene header and run this scene every minute using my Main scene FTBE:

  • Hi Sankotronic,

     

    Thank you for your reply and the coding, its much appreciated. 

     

    Just one thing, I would only want the pump to run (when it reaches temperature) between the hours of 8am until 10pm each day. Can you advise how best to code that?

     

    for information, sorry but I gave the wrong pump ID, it should be ID:1056

     

    Kindest regards

    Steve
